[−][src]Struct regex::CaptureMatches

pub struct CaptureMatches<'r, 't>(_);

An iterator that yields all non-overlapping capture groups matching a particular regular expression.

The iterator stops when no more matches can be found.

'r is the lifetime of the compiled regular expression and 't is the lifetime of the matched string.
